assi evaluiert; COPY ing system communicating with the lower end thereof extends upwardly through the stand A to the lower end of .the cylindrical feeder I, the upper portion of this pipe being provided with a valve O.

In order to pre-heat the return before it enters the water-heating section, and at the same tune, accelerate the low through this Feeder and consequently from the feeder through the water sections and the system, I lncrease the diameter of the Vlower portion of pipe-Hand take a pipe e from the upper end thereof and upwardly, around the lowermost heater then horizontally into the lower end o f the feeder I wherein it' is turned upwardly and provided with. a nozzle e4. I also take a second i le e from the concentrator J and extend it 1n loop form and in two sections as at eZ through the interior of the lower portion of pipeH the other endsof these pipe sectionsbeing bent as at e3 and located to discharge into the lower end of the feeder I. This pipe'e serves to conduct a small stream of water at a high temperature and ejects it into the lower end of the feeder, the ejected water raising the temperature of thewater i-n the feeder while the force of the ejection ac celerates the ilow. The pipe e meanwhile conducts a stream of water at a high temperature and the heat radiating therefrom raises the temperature of'the water returning through H. If desired the pipe e may be dispensed withif the circuit of the system is such as will insure the liow re uired.

The super-heater C is of vo utoid form, as shown in Fig. 7, and consists of an open flat bottom and curved top or hollow section having a spiral partition C therein, while the top thereof is cut away centrally and has the lower end of a cylindrical section 5F connected thereto at its lower end, and at its upper end to a distributer head G from which the flow pipes G of the heating system are taken.

The products of -combustion are conducted from the interior of the furnace to any available chimney connection and the heat thereof is utilized by radiation as follows: A pipe F is taken from the upper end of the interior of the furnace upwardly through the center of the super-heater and through the cylindrical section F and the distributer head G to the chimney, and the lower end thereof has a truncated cone M secured rigidly therein with its truncated apex facing upwardly' and its base closed and provided `with a damper M. The water is conducted from the concentrator J to the super-heater through a pipe R controlled by a valve It.

The supply of gas to the burners is controlled by the followingmeans: The gas is conducted to a distributer box T controlled by a valve T2 having a microm'etricl dial Til rconcentric to the stem thereof, and an index hand Fi? is mounted upon the valve stein and seiner? indicates ,upon the dial the different angular positions to which the valve is turned, thus v of the pipes of this series while said pipes arel controlled by valves V and the pipes S are controlled by valves S', the latter valves being provided with micrometric dials, and their stems with index lingers similarly to the valve T2. rPhis arrangement enables the burner members to be controlled either individually, by the valve V, by groups, by the-valves S or collectively by the valve T2.

In order to enable hot water to be provided for domestic use, I locate a water-heating section W similar to the sections, K, above the series of water-heating sections, and provide' same with flow and return pipes W and W2 respectively, which are connected to the hot water service pipes of the residence. I locate an independent burner X beneath this heater W and connect same to the distributer box T by a pipe X controlled by a valve X2. During the seasons when the furnace Ais in operation there will be no need to use the burner X as theheat from the burners beneath the other water-.heating sections will be sufficient; but at other seasons when the furnace will not be in operation, my invention provides for the independent supply of hot water for domestic use.

I make the water-heating sections of aluminium on account of its high efficiency as a heat conductor, and itsnot being liable to oxidation, and its natural rigidity which permit of very thin metal being used.

I prefer to arrange the heaters in close proximity to the water-heating sections in order to getas close as possible to the zone of heat generation, thereby obtaining the highest possible results from the heaters.
